I have update iredmail, including roundcube software. after that password change plugin doesn't work properly at the roundcube web gui.
I get on the password page:  could not save new password
at the log file i got:

MariaDB server version for the right syntax to use near '%D,passwordlastchange=NOW() WHERE username='user@domain.com'' at line 1 (SQL Query:
